To whom it may concern.'

Be it known that I, HARRISON B. WALTER,I

a citizen of the United States, and a lresident of Chicago, in thecounty of Cook and State of Illinois', have invented certain new anduseful Im rovements in Boxes; and'I do hereby dec are that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings and to the letters of reference marked th Thisinvention relates to improvements in boxes made of libre or aper boardand consists of the matters ereinafter described and more articularlypointed out in ,the ap ded c aims. is invention relates moreparticularly to the type of box shown in Letters-Patent No. 1,055,243,dated March 4, 1913, and No. 1,125,782, dated January 19, 1915,heretofore granted to me, said box comprising a tubuar body and recessedheads or'ends, each made from a blank with flap extensions at its foursides, folded at right angles and attached inside .the endof theytubular body.

The tubular body of a box of the kind is Amade preferably from a singleblank which is of a width equal to the total outside length vof the boxand whichis creased transversely at spaced intervals to provide foursides of the box, with a flap extension at one end of the blank to beattached to the part at the other end of the blank which makes with saidfla Ithe fourth side of the box.

f A box of t e kind is usually designed and intended for use as an endloader, in which case the -ilapextension last mentioned and the part tow ich it is to be attached to form the fourth side of the box, aresecured together, before the box is shipped to the packer. It ma I alsomanifestly be designed and used as a top loader in which case the partsforming the fourth side will be used as top closure flaps to be attachedto the flap extensions of the heads after thebox 1s loaded. .n

The object of the resent inventionvis to produce a-box of t le kindwhich is of eatly increasedv stren h at the ends or, Ereads of theboxand in which the heads I not` only present great rigidity to resistblows or jars tending to distort or cifush the box transversely but inwhich said heads are ereon, which form a `part of thisY specification.

' The relative widths of the more eilicientlyattached and sealedwithinthe ends of the box. o

The many advantages of the improved box will appear more fully as Iproceed with my s ecification.

In the rawingsz i' Figure 1 is `a perspective view showin the improvedbox as it appears when load and closed. Figure 2 is a plan view on anenlarged scale of a blank for making one of the heads lor ends of thebox.

Figure 3 represents on a still further enlarged scale a section throughthe blank" shown in Figure 2 in a plane indicated by the line 3-3 ofFigure 2.

Figure 4 represents a detail sectional view of one of the heads or lendsof the box adjacent the flap extension which is shownin folded right anar relationto the main -v blanE11 part vof the Figure 5 is a likesection showing said fla extension attached to one of the side wals ofthe tubular body of the box.

Figures 6 and 7 re resent detail', transverse sections of the b ankwhich forms the Vtubular body and of thetubular body itself.

Referring now to that embodiment'of the invention illustrated in thedrawings :-10

indicates the tubular body of the box and 11, lindicate the heads orends of the box. 12,13,14 and 15 indicate .the four sides of the tubularbody 11. 'The tubular body is made as shown' from a singleblank, creasedtrans.-

to define seetios of the blank correspon ing tolthe four sides of thebody, as thus enumerated, witha flap extension 15* at one end oftheblank adapted to underlie the section ending to the side 15 'and tobe attach thereto to complete the tubular body. arts 15 and 15f may bevaried as desired, t e part 15 being generally and preferably made ofthe complete width of the side of the body it is designed for,particularly in thv\e case of an end loading box.

` The heads or ends 11, 11 are each made of a, blank which has a mainbody ual to the area of the end of the box and sions 16 at its foursides which are folded .at ri ht angles to'said main body, and are attaced within the ends of the tubular body .against the sides of said body.

ap extenlos In creasing the blank which forms the tubular body 10, theold well known method of creasing bre or paper board is employed. Thatis to say, the blank is subjected to the action of dies or other toolswhich form a groove 17 on the face of the board, which faces inwardly.when the blank is folded, and a corresponding rib 17 f on the oppositeface of the board, namely the one which faces outwardl (See Figs. 6 and7.)

In creasing t e end blanks so that the flap extensions 16 may be foldedat right angles, a different method lis used. In this case, after theend blank has been cut, it is subjected to the action of dies or otherpressure devices by means of which the flap extensions 16 areforced intoand set in a plane which is offset somewhat from the plane of the mainblank as shown in Figure 3. And the plane into which said flapextensions are offset is on that side of the plane of the main blankwhich is opposite to the direction in which the fiap extensions aredesigned to be bent when applying the ends to the' tubular body 10.

The offsetting lof the flap extensions 16 in the manner describedproduces shoulders 16a which define the four sides of the main body ofthe end blank and which abut the severaljflap extensions 16 (see Fig.4:)4 when they are folded at right angles to the body of the blank 11and resist further bending or folding movement of said extensions.

Thus it'will be manifest that when the ends or heads 11 are inserted inthe tubular ends of the body, a substantially rigid, rightangular flangeabout the endv or head will be presented to efficiently resisttransverse blowslor jars tending to deform or break the box at its ends.

It will also be noted that with end or head blanks creased to permit thebending or folding of the flaps 16 as described, there is no shoulder orrib on the face of the flap extension, which is in contact with the wallof the tubular end of the body to which it is attached, so that anabsolutelyl f1 t contact between said parts is made possi le. (SeeFigure 5.)

other adhesive to attach the flap extensions of the head within thetubular body, thus securing the desirable advantages offanclose tightjoint which is to be attained by ace-l ment joint. I prefer, however, toprovide a jloint between the flap extensions 16 of the heads 11 and thetubular ends of the box, which consists of cement or adhesive and oftongues cut or otherwise formed and forced with the cement betweenbeyond the planes of the board parts from'which they are cut. Thisproduces a strong eicient joint, by means of which the fibre bodies'ofthe two boards are so connected at the points in the vicinity of thesaid tongues, that it may be well called ya fibre lock or fibre joint. f

Referring more particularly to Figure 5, 18 indicates the tongues cutfrom the ap extensions 16 and 19 indicates the tongues cut or partiallycut from the adjacent side of the tubular body. Preferably there are tworows of such pairs of tongues,one set, namely those indicated at 18 and19, being bent in one direction with reference tothe plane of the flapextension and the adjacent body wall and the other set 18, 19a beingbent in the opposite direction. The rows of tongues and the severaltongues cutv from. the board are spaced distances apart sufficient toprevent undue weakening of the board. The cement used inmaking the jointextends not only' over the undeformed or uncut contacting facescomprising the joint, but also over the contacting faces of the tongues;and to bring this'about, the tools or devices em loyed to cut or deformthe tongues are pre erably applied after the contacting faces of theparts forming the joints have been treated with the adhesive cement andat the time ressure is applied to bring the parts comprising the jointinto close joining relation.

The use of aforesaid joint or lock connecting the flap extensions of theheads or y ends of the box to the tubular body, is made feasiblebecause' of the fact ythat when the flap extensions are folded by themethod described there is no tendency to separate the laminee ofy theflap extensions, when they are folded to position, as is generally thecase when the creases for the flap extensions are made yas heretoforeand as illustrated in Figures 6 and 7. Thus the board of each of theflap extensions is a solid body j from` which efficient locking tonguesto produce'the` said joint ma'y be cut from said flap extensions, whichwould not be the caseA if the creases were formed as, for example, inthe way in which'they are made to provide the creases in the blank forthe ,tubular body. With fiat .engagement of the kind described, itispossible to use a cement or Whereas in describing my invention I havereferred to certain details of construction and arrangement it is to belinderstood that the invention is not limited thereto `except as may bepointed out in the appended claims. j
